Great job.

The spec gets a bit tricky when handling multiple files - see:
seq 3 | awk '{ print $1 > $1 }'
head -n1 $(seq 3)

This is simple enough to do in awk, with very few lines of code.

I'd argue that requiring awk to use `head` would create more
complexity(for the end user) than it would solve for the developer.
